7. Clean the timing degree scale and mark the notch on the front crankshaft pulley with a white crayon. (Figure E). Start the Engine. Increase the engine speed to 1600 rpm and check the ignition timing. If necessary, adjust the the timing to the specification listed on the Emission Control Label (typically 15 degrees plus or minus 1 degree BTDC and for High Altitude cars 21 degrees plus or minus 1 degree BTDC). You must loosen the distributor hold-down clamp in order to gradually rotate the distributor to achieve the correct timing. Tighten the distributor hold-down clamp and verify timing is correct.

Turn off the engine and remove the timing light. Reconnect the hose to the distributor vacuum mechanism. Reconnect the wire connector to the vacuum switch assmebly. Leave the tachometer connected for the next section.

Setting Fast Idle Speed

1. Disconnect and plug the EGR vacuum hose (D) (Figure F).

2. Place automatic transmission in the PARK position and manual transmission in the NEUTRAL postion.

3. Start the engine.

4. Position the fast idle speed adjustment screw (E) (Figure G) in contact with and against the shoulder of the SECOND step (F) of the fast idle cam.

6. Remove the fast idle speed ajustment screw from the fast idle cam and allow the engine to return to curb idle speed.

7. Turn ignition to OFF.

8. Reconnect the vacuum hose to the EGR valve.

Curb Idle Speed and Sole-Vac Throttle Positioner

NOTE: During this operation you should consider having a second person assist you.

1. If your Sole-Vac accuator is equipped with a vacuum hose remove it and plug (G) (Figure H)

2. Disconnect the Sole-Vac holding solenoid wire (H) (Figure I).

3. Start the Engine.

4. Have your helper set the parking brake and also depress the service brake. Manual Transmission cars are to be placed in NEUTRAL and Automatic Transmission Cars placed in DRIVE. If you do not have a helper make sure to firmly block the wheels and set the parking brake.

5. Have your helper (or you) increase the engine speed to above 1200 rpm for 3 - 5 seconds and then allow the engine to return to curb idle speed.

11. All cars With a jumper wire, apply battery voltage (12V) OR reconnect the holding solenoid wire connector back to the Sol-Vac THEN disconnect the air conditioner compressor clutch wire and then turn the A/C on (too cold and fan on). Either method will energize the holding solenoid.

12. Hold the throttle open manually to allow the Sole-Vac throttle positioner to fully extend.
NOTE: On cars without the vacuum line the positioner should extend on its own. You must do this on cars with the vacuum line.
